Emergency treatment of pelvic ring injuries: state of the art.

Arch Orthop Trauma Surg

October 2024

Department of Orthopaedic and Trauma Surgery, University of Leipzig, Leipzig, Germany.

High energy pelvic injuries sustain significant mortality rates, due to acute exsanguination and severe associated injuries. Managing the hemodynamically unstable trauma patient with a bleeding pelvic fracture still forms a major challenge in acute trauma care. Various approaches have been applied through the last decades.

Microstructural analysis on the innervation of the anterior, medial, and lateral human hip capsule: Preliminary evidence on its neuromechanical contribution.

Osteoarthritis Cartilage

November 2023

Division of Macroscopic and Clinical Anatomy, Gottfried Schatz Research Center, Medical University of Graz, Graz, Styria, Austria; Division of Biomechatronics, Fraunhofer Institute for Machine Tools and Forming Technology (Fraunhofer IWU), Dresden, Saxony, Germany; Department of Orthopaedic and Trauma Surgery, University of Leipzig, Germany.

Objective: Capsular repair aims to minimize damage to the hip joint capsular complex (HJCC) and subsequent dislocation risk following total hip arthroplasty (THA). Numerous explanations for its success have been advocated, including neuromuscular feedback loops originating from within the intact HJCC. This research investigates the hypothesis that the HJCC contributes to hip joint stability by analyzing HJCC innervation.

Introduction: The aim of this review was to summarize the available evidence for biomechanical stability following surgical DOB reconstruction, and to determine whether distal radioulnar joint (DRUJ) stability with a reconstructed DOB was similar to the native intact condition or that after the Adams procedure.

Material And Methods: A systematic literature search according to the PRISMA guidelines was performed using the databases PubMed and Embase. The following search algorithm was used: ("DOB" OR "Distal Oblique Bundle") AND "Reconstruction".

Two fingerbreadths, one finger's width: on the proximity of the radial nerve to the deltoid tuberosity.

Arch Orthop Trauma Surg

August 2023

Department of Trauma Surgery, State Hospital Feldbach, Fürstenfeld, Ottokar-Kernstock-Straße 18, 8330, Feldbach, Austria.

Introduction: The aim of this study was to find a convenient technique to evaluate the location of the radial nerve (RN) with reference to the deltoid tuberosity (DT).

Materials And Methods: Sixty-eight upper extremities, embalmed using a modified version of Thiel's method, were included in the study. The interval between the tip of the greater tubercle of the humerus and the distal tip of the lateral humeral epicondyle (LE) was defined as humeral length (HL).

Most motion planners generate trajectories as low-level control inputs, such as joint torque or interpolation of joint angles, which cannot be deployed directly in most industrial robot control systems. Some industrial robot systems provide interfaces to execute planned trajectories by an additional control loop with low-level control inputs. However, there is a geometric and temporal deviation between the executed and the planned motions due to the inaccurate estimation of the inaccessible robot dynamic behavior and controller parameters in the planning phase.

Purpose: In the last decades, total elbow arthroplasty, elbow osteosynthesis and revision surgery have been more popularized. The study aimed to assess the course of the anconeus branch of the radial nerve in relation to two variations of the lateral para-olecranon approach, considering iatrogenic nerve injuries.

Methods: The study consisted of 120 upper extremities from 60 Thiel-embalmed human specimens.

Article Synopsis
  • The study aimed to determine the projected location of the musculocutaneous nerve (MCN) entry point into the coracobrachialis muscle relative to the length of the humerus.
  • Sixty-six upper extremities were analyzed to measure distances between anatomical landmarks such as the greater tubercle (GT) and the medial and lateral epicondyles, which helped establish proportions for localization.
  • Findings indicated that the MCN entry point is typically located between 14.9-33.9% of the humeral length from the GT, and 14.2-34.4% from the coracoid process, providing useful intervals for surgical procedures.

An enlarged anastomosis connecting the vascular territory of the external iliac and the obturator artery may replace most or all of the latter. This relatively common vascular variation, known as Corona mortis, can lead to death in the worst-case scenario if injured. Despite being well-known, exact anthropometric data are lacking.

The foot comprises of active contractile and passive connective tissue components, which help maintain stability and facilitate movement during gait. The role of age- or pathology-related degeneration and the presence of fat within muscles in foot function and pain remains unclear. The existence of fat has to date not been quantified or compared between individuals according to age, sex, side or subregion.

Detailed understanding of the innervation of the hip capsule (HC) helps inform surgeons' and anaesthetists' clinical practice. Post-interventional pain following radiofrequency nerve ablation (RFA) and dislocation following total hip arthroplasty (THA) remain poorly understood, highlighting the need for more knowledge on the topic. This systematic review and meta-analysis focuses on gross anatomical studies investigating HC innervation.

The hip joint capsule contributes to the stability of the hip joint and lower extremity, yet this structure is incised and often removed during total hip arthroplasty (THA). Increasing incidence of osteoarthritis is accompanied by a dramatic rise in THAs over the last few decades. Consequently, to improve this treatment, THA with capsular repair has evolved.
